LUBRICATORQ SPECIFICATION brmillg parli', 0f Letters Patent N0. 679,246, dated July 23, 1901. Application led February Z5, 1901. Serial No. 48:70L (N0 111051610 To all whom, t may concern:

Be it known that I, JOHN J. TUNNEY, a citizen of the United States of America, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this speciiication.

This invention relates to certain new and useful improvements in lubricators, and has for its object the provision of novel means whereby a certain quantity of oil is automatically fed to a bearing at each revolution of a shaft.

The invention further ailns to construct a device of this character which will possess advantages in points of simplicity, strength, durability, and cheapness.

Furthermore, the invention aims to conperfect in its op; eration at all times.

With the above and other objects in view the invention consists in the novel combination and arrangement of parts to be hereinafter :more fully described, and specifically pointed out in the claims.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate corresponding parts throughout `the Vseveral views, in whic Figure 1 is a side elevation of the shaft and bearing having arranged thereon my iinproved lubricator, the latter being shown in vertical section. Fig. 2 is a vertical sectional View of the lubricator detached. Fig. 3 is a front elevation of the stem. Fig. 4 is a side elevation of the nipple. Fig. 5 is a like view of the same, taken at right angles to Fig. 4. Fig. 6 is an inverted plan view of the nipple.

In the drawings the reference-numeral l indicates a shaft, and 2 the hub of a pulley having secured thereto the annular sectionring 3, carrying the upright arm 4. The reference-numeral 5 represents the cone-shaped fitting carrying interiorlyscrew threaded flange 6 to receive .the spherical casing 7,

which has an upwardly-extending screwthreaded portion S. The reference-numeral i) indicates an interior hollow stem having a central opening l0 arranged therein and terminating at its lower extremity in a nozzle l1, extending through the cone-shaped fitting 5. This stem is provided near its upper end with ports 12, extending transversely to the central opening 10 and communicating therewith. The said stem has secured near its lower end a weight 14, which is normally adapted to rest in the cone-shaped fitting 5. The reference-numeral l5 represents a nipple having arranged therein ports 16, which are adapted to register with the ports 12 as the stem travels downwardly with each revolution of the lubricator, the said nipple having formed integral therewith at its upper extremity a head 17, which is adapted to rest upon the upper end of the upwardly-extending screw-threaded portion 8X of the spherical casing, the said nipple being held in position by means of the screw-threaded cap 18 engaging the exteriorly screw.- threaded portion of the extension. The said cap is likewise held in position by means of the spring-arm 19, secured at 2O to the arm 4. The reference-numeral 21 represents slots arranged in the nipple, which extend in alinement therewith and form guideways for the reception of pins 22, secured to the hollow stem. The reference-numeral 23 indicates a spiral spring encircling the said stem, this spring being seated between the lower extremity of the nipple and the upper end of the weight.

The operation of my improved lubricator is as follows: With each revolution of the shaft and pulley the shaft 1 will tend to depress the spring 23, thereby forcing the stem downwardly to a point where the transverselyextending ports 12 will register with the ports 16 and allow the oil contained in the spherical lcasing or receptacle to enter the ports 16, into the port l2, down through the opening l0, and discharge by the nozzle 1l upon the shaft l. As the shaft revolves the ports will again automatically close, caused by the gravity of the weight, the pins serving to guide the stem in the proper manner. It will IOO be seen that the valve will be operated in this mannerv intermittently on each revolution of the shaft and that only a small amount of lubricant will be fed in the proper channels with each revolution.

It will be noted that various changes may be made in the details of construction with- -out departing from the general spirit of my invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a lubricator, the combination with a cone-shaped fitting adapted for attachment to the hub of a pulley, a spherical casing secured to said cone-shaped fitting, a nipple connected to the upper end of said spherical casing and having arranged therein ports, ahollowr stem in which are arranged openings extending transversely thereto and adapted to register lwith the ports formed in the nipple, a weight arranged on said stem, a spiral spring encircling the said stern between said nipple and weight, a screw threaded cap adapted to hold said nipple in position, substantially as described.

2. In a lubricator, in combination with` a cone-shaped fitting adapted for attachment to the hub of a pulley, a spherical casing secured to said cone-shaped fitting, a nipple carrying a head and having formed therein a port, slots arranged in said spherical casing, a stem having a central opening and transversely-extending ports communicating therewith, pins arranged on said stem adapted to operate in said slots, a weight secured to said stem, a spiral spring encircling said stem, and a cap arranged upon the upper end of said spherical casing, all parts being arranged and operating substantially as described.

In testimony whereot' I have hereunto af xed my signature in the presence of two subscribing witnesses.

JOHN J. TUNNEY.
